Organization is key!


Do you lose stuff in your bedroom? Have you spent countless hours looking for that lost sock or that missing piece of Ms. Johnson's homework? If so, then you need ORGANIZATION! Science is all about organization. Your Mastery Assessment is to create an an infomercial with the purpose of selling the periodic table to a group of very unorganized scientists.


What should you know?

  1. What is an element? An element is a substance that is made entirely from one type of atom. (http://education.jlab.org/qa/element.html)
  2. What are elements made of? The atom is made of tiny bits of energy called subatomic particles, and each type of atom has a different number of particles. (http://www.dmturner.org/Teacher/Library/5thText/ChemPart3.htm) The number of protons makes a element different. Hydrogen has 1 proton and helium has 2 protons.
  3. How are elements different from each other? Just as people not only look different from each other but also interact differently with others, so elements have both physical and chemical properties. (http://www.aip.org/history/curie/periodic.htm)
  4. How many different elements are there?There are 117 different elements(http://education.jlab.org/qa/element.html)
  5. In terms of chemistry--what is a property? Is a characteristic of a pure substance that describes its ability to change into different substances. ( North Carolina Grade 8 Prentice Hall Science Explorer )
  6. How are elements on the periodic table grouped? Why? Elements on the periodic table are grouped by how many protons they have. ( North Carolina Grade 8 Prentice Hall Science Explorer)
  7. What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? A group or family is a vertical column in the periodic table. The horizontal rows of the periodic table are called periods. Why Periodic Table important because it inquiry that lead to our current understanding of the elements and their physical properties.

  8. What are the features of the periodic table? (How do you read it?) Each column is a family (North Carolina Grade 8 Prentice Hall Science Explorer)


Mastery Assessment

Deadline: 3/2/2010
Science Rocks, Inc. has hired you for a marketing assignment. You and your team have been tasked with creating an infomercial with the purpose of selling the periodic table to a group of unorganized scientists. They see nothing wrong with the way they keep their elements "organized" so you must point out every feature of the periodic table to prove to them they need this tool.
